Three RCTs showed that rubber band ligation was better than injection sclerotherapy in a variety of outcomes (pain, repeat treatment, prolapse, bleeding) in persons with mainly second-degree hemorrhoids; however, rubber band ligation was associated with more immediate adverse effects.
Edema is the medical term for swelling. Body parts swell from injury or inflammation. It can affect a small area or the entire body. Medications, infections, pregnancy, and many other medical problems can cause edema. Edema happens when your small blood vessels become leaky and release fluid into nearby tissues.
Diseases and conditions that may cause edema include: Congestive heart failure. When one or both of your heart's lower chambers lose their ability to pump blood effectively â as happens in congestive heart failure â the blood can back up in your legs, ankles and feet, causing edema. Heart failure can also cause swelling in your abdomen.
